KEK Open House 2025

The High Energy Accelerator Research Organization (KEK) held its Open House 2025 on Tuesday, September 23, 2025. Many visitors attended the event, where they had the opportunity to experience the forefront of scientific research and advanced technologies.
At the four centers of the Applied Research Laboratory—the Radiation Science Center, the Computing Research Center, the Cryogenics Science Center, and the Mechanical Engineering Center—visitors enjoyed facility tours and interactive, hands-on programs. A stamp rally and a puzzle-solving challenge were also organized, providing fun and engaging ways for participants to explore the world of research.

Radiation Science Center
The center exhibited and demonstrated radiation detectors capable of measuring radiation in everyday environments, allowing visitors to try radiation measurement for themselves.

Computer Research Center
The center introduced its activities through videos, slides, and panels, explaining how KEK’s computing and network infrastructure supports research activities. Topics included the use of grid technology to effectively utilize computational resources worldwide, and simulations of radiation and elementary particles.
This year also marked the debut of an AI-powered Open House Concierge.
The Central Computer Machine Room Tour was held five times, attracting more than 300 participants in total.

Cryogenics Science Center
Through clear explanations, visitors learned about the mechanisms of superconducting materials and magnets. The “Superconducting Coaster” demonstration allowed them to experience the fascinating properties of superconductors firsthand.

Mechanical Engineering Center
In addition to demonstrations of machine tools and presentations of research achievements, visitors enjoyed hands-on activities such as a vacuum drop experiment and remote-controlled trolley demonstrations. These activities were enjoyed by participants of all ages, from children to adults, highlighting the excitement of science and engineering.

Stamp Rally
A stamp rally connecting all four centers was also held. Using 2,000 prepared pamphlets, many visitors enjoyed collecting stamps while touring the facilities. This family-friendly activity was very popular, offering both children and adults an enjoyable way to explore scientific facilities while learning about research.
